Bunnyman (2011)

Bunnyman is the story of a group of friends on their way back from a spontaneous weekend trip to Las Vegas, and while driving through the remote regions of southern California they suddenly find themselves in a sickening game of cat and mouse with a five ton dumptruck and, when looking for help, stumble upon a nightmarish family who takes pleasure in dismembering and eating as many of the kids as possible.

Unfortunately the movie Bunnyman is not yet available on HBO Max.
